Organic search remains the largest traffic source for most industries, at roughly 40-60% of trackable visits depending on vertical. (BrightEdge / Semrush industry analyses)
The median small-business website receives roughly 1,000-10,000 visits per month — a range so wide that vertical benchmarks matter more than global averages. (Multiple SMB analytics studies)
Professional services sites (legal, accounting, consulting) typically see 60%+ of traffic from organic search — the highest organic dependence of any major vertical. (Ruler Analytics / industry channel studies)
E-commerce sites show the most diversified mix: organic commonly 30-40%, with paid, email, social, and direct making up the majority. (Semrush / Statista e-commerce analyses)
Average engagement rate (GA4) across industries sits near 50-60%, with B2B services at the higher end and publisher/content sites lower. (GA4 benchmark aggregators, 2025-2026)
Mobile generates roughly 64% of organic visits overall, but B2B verticals still see 50%+ desktop share during business hours. (BrightEdge / SimilarWeb aggregates)
Ranges reflect typical small-to-mid-market sites, not category leaders. Panel-measured figures (SimilarWeb-style) and analytics-measured figures differ; treat these as directional bands.
Local service businesses (trades, home services, clinics): a healthy site typically draws 1,000-5,000 visits/month, with top local performers reaching 10,000-20,000+. (Source: Ottawa SEO Inc. client portfolio analysis (2026))
Professional services (legal, accounting, consulting): typical SMB sites see 2,000-10,000 visits/month; content-led firms reach 25,000-100,000+. (Source: Industry benchmark aggregations / Ottawa SEO Inc. analysis (2026))
E-commerce SMBs commonly operate in the 10,000-50,000 visits/month band; mid-market stores run 100,000-500,000+. (Source: Semrush / Statista e-commerce traffic analyses)
B2B SaaS: seed-to-Series-A companies typically see 5,000-30,000 visits/month; content-strong mid-market SaaS reaches 100,000+. (Source: SaaS marketing benchmark reports, multiple sources)
Restaurants and hospitality skew heavily to discovery on Google Maps and social rather than websites; 500-5,000 site visits/month is typical for single-location operations. (Source: Local marketing industry analyses)
Media and publisher sites are the outlier vertical: even niche publishers routinely exceed 100,000 visits/month, driven by content volume. (Source: SimilarWeb / publisher industry data)
Organic search delivers roughly 40-60% of trackable visits for most industries — the single largest channel in nearly every vertical. (Source: BrightEdge / Semrush industry analyses)
Professional services show the highest organic dependence, with 60%+ of visits from organic search in multiple channel studies. (Source: Ruler Analytics channel benchmarks)
E-commerce runs the most diversified mix: organic 30-40%, with paid search, email, social, and direct sharing the remainder. (Source: Semrush / e-commerce channel studies)
Direct traffic (brand strength proxy) typically contributes 20-30% of visits across verticals — higher for established brands. (Source: Multiple channel-mix analyses)
Social media contributes a smaller share of website visits than most owners expect — commonly 5-10% outside of media, fashion, and food verticals. (Source: Ruler Analytics / channel benchmark studies)
AI-engine referrals (ChatGPT, Perplexity, Gemini) remain under 5% of visits for most sites in 2026 but are the fastest-growing channel line, roughly doubling year-over-year. (Source: Ottawa SEO Inc. client portfolio analysis (2026))
Average GA4 engagement rate across industries sits around 50-60%; B2B services trend higher, publishers and blogs lower. (Source: GA4 benchmark aggregators, 2025-2026)
Average session duration across industries clusters around 2-3 minutes, with long-form content sites exceeding 4 minutes. (Source: Multiple analytics benchmark studies)
Organic search visitors view more pages per session and convert at higher rates than social visitors in nearly every vertical studied. (Source: Ruler Analytics / channel quality studies)
Mobile accounts for roughly 64% of organic visits overall, but B2B sites still see half or more of weekday traffic from desktop. (Source: BrightEdge / SimilarWeb aggregates)
Sites publishing 4+ quality posts per month grow organic traffic materially faster than sites publishing sporadically — content cadence is the strongest controllable growth variable. (Source: HubSpot / content frequency studies)
Service businesses that publish per-neighbourhood or per-city landing pages capture 2-4x more long-tail organic traffic than single-page equivalents. (Source: Ottawa SEO Inc. analysis (2026))
Quarterly content refreshes correlate with significantly higher AI citation share and recovered rankings on decaying pages. (Source: Ottawa SEO Inc. 2026 SMB Benchmark)
Sites in the top quartile of their vertical's traffic band hold 3-5x more ranking keywords than the median site — keyword breadth, not luck, separates the bands. (Source: Semrush / Ahrefs visibility analyses)
Benchmark against your vertical's band, not global averages — 3,000 visits/month can be excellent for a trade business and alarming for e-commerce.
Organic search is the largest channel in nearly every industry; underinvesting there caps the whole traffic mix.
Watch engagement rate alongside volume — traffic that doesn't engage is a content-fit problem, not a win.
Add an AI-referral line to your reporting now; it's small but doubling annually.
To climb a band: publish consistently, build keyword breadth, and refresh decaying content quarterly.
It depends on vertical: 1,000-5,000 monthly visits is healthy for a local service business, professional services firms typically want 2,000-10,000, and e-commerce needs 10,000+ to sustain meaningful revenue. The better question is trend and conversion: growing traffic that produces leads beats large static traffic that doesn't.
For most industries, organic search should be the largest single channel at roughly 40-60% of visits. Professional services often exceed 60%. If organic is under a third of your traffic and you're not deliberately paid-led, there's usually meaningful SEO headroom.
Panel-based tools like SimilarWeb estimate from browsing panels and models, while GA4 measures actual tagged sessions — they routinely disagree by 30-50%+, especially for smaller sites. Use your own analytics for truth and third-party tools only for competitor-relative comparisons.
Estimate it with panel tools (SimilarWeb, Semrush Traffic Analytics) but read them as relative signals, not absolutes — small-site estimates are noisy. A more reliable competitive proxy is ranking-keyword count and visibility trend, which correlate strongly with traffic bands.
Yes, as a small but fast-growing line: most sites see under 5% of visits from AI referrers (ChatGPT, Perplexity, Gemini) in 2026, roughly doubling year-over-year in our portfolio. AI Overview citations also drive visits that report as google.com referrals, so the true AI-influenced share is higher than the referrer line shows.
